Abdominal lymphadenopathy in sarcoidosis.

Medical records of 370 patients with sarcoidosis were reviewed. Of these, 32 had a computerized tomographic (CT) and/or ultrasound (US) examination of the abdomen. Two patients had extensive abdominal adenopathy: one was diagnosed by CT and the other by US. Both patients had conventional chest radiographic findings characteristic of sarcoidosis. In addition, five patients had hepatosplenomegaly; three had only hepatomegaly; three had only splenomegaly. There exists a small and previously unsuspected incidence of patients with extensive abdominal adenopathy in sarcoidosis. Although lymphoma and metastatic disease are far more common causes of extensive abdominal lymphadenopathy, sarcoidosis should be considered in the appropriate clinical setting. In many cases, correlation with conventional chest radiographs may be confirmatory.
